3 Claims. (Cl. 301- 13) This invention relates to a dual tired wheel, and Before the stop ring '7 has been put in place the the invention is particularly adapted for use in inboard tire-rim 8 can be readily slipped over the connection with truck wheels. The general object shoulder 6 from the outboard side. This rim is of the invention is to produce a wheel of this type of standard form and is provided at its outboard which will be of relatively light weight, but which edge with an inclined, or conically curved, seat 60 will afford means for readily putting the tire rims face 9 that seats upon the conically curved seat 3 in place upon it; also to provide a wheel of this so that the inboard portion of the rim overhangs type in which the inboard and outboard tire rim the inboard side of the wheel. seats are so constructed as to enable tire rims to This rim is secured in place by clamping means 10 be used which are duplicates of each other in conmounted on the wheel adjacent the seat 3 and 65 struction. This enables standard tire rims to be constructed so that the same is accessible from a used readily in inboard or outboard positions. point posed towards the axis of the wheel. In

Further objects of the invention will appear The axes of these studs are inclined, as indihereinafter. cated in Figure 1, so that they extend towards the The invention consists of novel parts and comaxis of the wheel at the outboard side. On these bination of parts to be described hereinafter, all studs ordinary nuts 13 can be applied which seat 75 of which contribute to produce an efficient dual up against ordinary clamping lugs 14, the edges of tired truck wheel. the lugs engaging the outboard edge of the rim 8.

In addition, I provide a keeper ring 1'7 that dual tired wheel embodying my invention.

In the tion of the inner edge, or rim, of the wheel at its present instance, this keeper ring is formed with inboard side. an inclined or conically curved outer face 19 that In practicmg the invention I provide a wheel engages the seat face 18 and constitutes a seat for 0 which is preferably adapted to be made of cast the outboard rim. In order to secure the outsteel and embodying in its construction a hub 1, board rim in place clamping studs 20, or other with spokes 2. Preferably in line with the plane means, is provided on the outboard edge of the of the spokes 2, I provide the wheel rim with an wheel.

Similar driving lugs 25 are provided on the inner face of the outboard rim and these are received in a wide shallow groove 26 (see Figure 2) formed in the outer face of the wedge ring.

It is not necessary that the inner diameter of the stop ring 7 should fit accurately to the diameter of the wheel at the cylindrical face 5. However, this ring should be a stout solid ring of steel and is preferably not a split ring. The wedge ring 17 is also preferably not of split ring type.

There may be as many of the studs 10 and studs 20 as are desired. At the points Where the studs 10 are located the rim 4 of the wheel is formed with an opening 27 to make clearance at this point for the lugs 14 and the clamping nuts 13.

It is understood that the embodiment of the invention described herein is only one of the many embodiments this invention may take, and I do not wish to be limited in the practice of the in vention, nor in the claims, to the particular embodiment set forth.

What I claim is:

1. A dual-tired truck wheel having a body with a single integral inboard felloe having a substantially conically curved seat with the small end of the cone of the seat disposed toward the outboard side of the wheel, said inboard felloe having clamping studs for the inboard tire rim mounted in the same adjacent to the inboard tire rim seat and disposed adjacent to the smaller end of said inboard seat with their axes inclining toward the axis of the wheel, said wheel having a single outboard seat with means for securing an outboard tire rim upon the same.

2. A dual-tired wheel having an integral wheel rim with an outboard felloe with an integral annular shoulder, a continuous stop-ring seating against said shoulder, means cooperating with the stop-ring for securing an outboard tire rim on the wheel, said wheel having an integral inboard seat located toward its inboard side to receive the inboard tire rim from the outboard side of the wheel, passed over the said outboard felloe before the stop-ring is put in place, said wheel having an open space between the outboard felloe and the inboard felloe, clamping studs with clamping nuts located radially inward from the inboard seat with their axes located in an inclined direction and extending toward the axis of the wheel at the outboard side, thereby rendering the clamping nuts accessible at all times from the outboard side of the wheel and from a point within the radius of the outboard felloe, and lugs carried by the inclined clamping studs and projecting radially outward into the said space for engaging the outboard edge of the inboard tire rim to secure the same on its seat.

3. A dual-tired truck wheel having a body with a single integral inboard felloe having a substantially conically curved seat with the small end of the cone of the seat disposed toward the outboard side of the wheel, said inboard felloe having clamping studs for the inboard tire rim mounted in the same adjacent to the inboard tire rim seat and disposed adjacent to the smaller end of said inboard seat with their axes inclining toward the axis of the wheel, said wheel having a cylindrical face toward its outboard side with an annular shoulder located at the inboard end of the cylindrical face, said shoulder having a stop face located in a plane substantially at right angles to the axis of the wheel, a continuous stopring seating against said shoulder, and means for clamping an outboard tire rim against said continuous stop-ring, said shoulder being of a diameter to permit the inboard tire rim to be passed over the outboard end of the wheel before the stop-ring has been put in place.
